玫瑰露葡萄新梢同侧或异侧留1～2果穗,从盛花前1周到盛花后3周,每周一次,观察基部10片叶~(14)C-同化物向果穗的分配。结果表明:随着新梢上果穗数的增加,~(14)C 从叶片输出的百分比和向果穗分配的百分比都逐渐增加.所有的果穗主要从它同侧的叶片上获得~(14)C-同化物,而从异侧叶获得的很少.根据新梢单叶~(14)C-同化物向果穗分配的百分比,可计算出新梢每侧叶供给果穗生长的~(14)C-同化物为69%～90%(平均为84%),而与果穗在新梢上着生的位置无关。
Rose dew shoots new shoots ipsilateral or heterosexual leave 1 to 2 ears, from the first bloom to 3 weeks after full bloom once a week, observe the base of 10 leaves ~ (14) C-assimilates to the ear distribution. The results showed that the percentage of ~ (14) C output from the leaves and the percentage of allocation to the ear increased with the increase of the number of ears on the shoots, and all the ears were mainly obtained from the leaves of its ipsilateral leaves. - assimilates, and very little from the isolateral leaves.According to the percentage allocation of shoot- to (14) C-assimilates to shoots in shoots, the ~ (14) C - The assimilates range from 69% to 90% (average 84%), irrespective of where the ear is born on the shoot.
